INTRODUCTION 


HE General Electric Com- 
pany occupies an unique 
position in the electrical 
business in that it can 
furnish from its own shops, 
every electrical device 
necessary for the complete 
installation of an electric 
lighting and power plant. 
Prospective purchasers will find it desir- 
able to place their orders with one con- 
cern, as by so doing responsibility is not 
divided, and a complete, uniform, stand- 
ard outfit will be obtained. 

The demand for apparatus for 
isolated lighting has increased continually 
since the introduction of the incandescent 
lamp, and electric light is now universally 
conceded to be the only form of artificial 
light suitable for the illuminating of fac- 
tories, creamertes, mills, machine shops, 
breweries, country residences, country 
clubs, sugar plants, plantations, cotton 
compresses, etc. Every such institution 
should use electric light for artificial 
illumination, not only on account of the 
satisfactory quality of the light which is, 
of course, unrivaled, but because of the 
remarkable convenience with which it 
may be installed and operated. Beside 


5 


GENERAL ELECTRIC COMPANY 


these advantages, there are the low 
cost of operation and maintenance, and 
the decreased insurance rates obtained 
where electric lighting supersedes other 
types of illumination. If it is impossible 
to secure service from a nearby central 
station, it is wise to install a complete 
electric plant on the premises. 

In the pages following is given a 
general description of the various devices 
manufactured by the General Electric 
Company, which are necessary for a com- 
plete installation. If information in 
detail is desired on any of these devices, 
the Company will be very glad to mail 
it upon application to the nearest sales 
office. 

All material recommended by the 
General Electric Company has_ been 
approved by the Fire Underwriters.

epue General Electric Company has 
for many years supplied all the 
engines and generators for the United 
States Navy. These engines are so 
uniformly satisfactory that a de- 
mand has arisen for sim- 

ilar sets for commercial 
work, particularly in 
isolated plants.

of such sets are

with these engine-generator sets will be 
able to buy from the General Electric 
Company everything required for the 
installation excepting only the boiler 
equipments. The generators are mount- 
ed directly on the engine bed-plate and 
their design and construction are par- 
ticularly compact.

marked success. All the moving parts

apes General Electric Company is the

years manufactured incandescent lamps 
for every purpose, and its present 
product represents an evolution, the 
lamps being universally regarded as 
most suitable for each class of work for 
which they are supplied. Standard 
lamps for ordinary lighting purposes can, 
of course, be supplied in any desired 
voltage, 16 C. P. being 
most inuse. If, how- 
ever, lamps are desir- 
ed for any particular 
purpose such as signs 
or decoration, a lamp 
especially built for 
these purposes will be 
supplied. Any manu- 
facturing establish-

benefitted by using 
permanent electric 
signs and _— special 
lighting on certain 
occasions, all of this 
being easily and 
economically accomplished by the use 
of Edison lamps made for the particular 
purpose required.

bee lamp sockets and receptacles 
required in isolated plants may all 
be purchased from the General Electric 
Company, which manufactures a line of 
these devices, covering every conceivable 
requirement. This includes sockets for 
drop lights, weatherproof sockets for 
damp places, porcelain sockets for dye- 
houses and places where acid fumes are 
present, and porcelain lamp receptacles for 
both concealed wiring and cleat wiring. 
Portable incandescent lamp holders are 
convenient and can be supplied by this 
Company. Socket bushings, cord ad- 
justers, attaching plugs, shade holders 
and all of the various small supplies 
required with incandescent lighting can 
also be furnished. 
When installing an isolated plant,

This the General Electric Company 
manufactures in its own shops in Schen- 
ectady. Besides the enormous quantities 
required in the manufacturing of its own 
apparatus, it regularly sells a large 
amount of all sizes of insulated wire, 
cable and flexible lamp cord for all kinds 
of construction. The Company’s shops 
for this work are as fine as any in the

country.. It is evident, therefore, that 
persons contemplating the installation of 
an isolated plant will do well to secure 
also their wire and cable from the 
company manufacturing their generators 
and other electrical apparatus. The 
General Electric Company has also its 
own porcelain works, and regularly ships 
porcelain insulators of all kinds. For 
ordinary construction, certain insulators 
of peculiar design are manufactured 
exclusively by this Company.

USEFUL INFORMATION 


Incandescent lamps are made in 
three efficiencies known as 3.1; 3.5 and 
4 watts per candle. 

Thus a 16 candle-power 3.1 watt 
lamp consumes 49.6 watts or practically 
50 watts. A 16 C. P. 3.5 watt lamp 
consumes 56 watts. A 16C. P. 4 watt 
lamp consumes 64 watts. 

For ordinary isolated plants we 
recommend the 3.5 watt lamp. 

A kilowatt equals 1000 watts, so a 25 
Kw. dynamo would have a capacity of 
25000 

56 
allowing for any losses in the lines. If 
3.1 watt lamps are used a greater number 
can be connected. 

Example : 

Find dynamo capacity required to 
supply 325-16 C. P. 3.5 watt lamps allow- 
ing 10% losses 

325 X16 X 3.5 = 18200 watts = 90% 
total watts 

18200 

.9O 

In mills of various kinds it is cus- 
tomary to allow 5% loss in feeders from 
the dynamo to the center of electrical 
distribution, and 2% loss in the mains 
from which the lamps are served.

001”) gives the circular mils. 

M=Circular Mails. 

C= Current in Amperes, 

D=Average Distance Current is 
transmitted one way. 

P=Per Cent. Loss allowed. 

21—Constant. 

To ascertain size of wire 

mM—CXPX21 
R 

Example: 

Find size of wire necessary to trans- 
mit current for 200-16 C. P. 3.5 watt 
lamps at 120 volts dynamo pressure a 
distance of 600 feet, allowing 5% loss 

5% of 120 volts=6 volts which will 
give I14 volts at center of distribution. 
Allowing 2 volts more for losses in the 
mains and services we would use 112 volt 
incandescent lamps 

So 200 X 10 X3.5 

rr 

MOORE 2 T= 210000. 

By referring to the table on next 
page it will be found a #0000 wire is the 
correct size. 


—=100 amperes
